Laminate Flooring Calculator: measuring notes and method
Measure rooms without overlap
Divide L-shaped rooms into non-overlapping rectangles, then add their areas. Combine rooms only when the same product and layout apply.
Check pack coverage and pattern
Minimum end-piece lengths and patterned layouts can reduce usable yield. Underlay, thresholds and skirting require their own quantities.
CHECK A PRACTICAL EXAMPLE
Check the exact pack before comparing prices
The room is 22 m² with a 10% cutting allowance. These are illustrative pack sizes.
2.2 m² per pack
- Flooring packs to buy
- 11
- Area with waste
- 24.2 m²
2.5 m² per pack
- Flooring packs to buy
- 10
- Area with waste
- 24.2 m²
Compare the cost of whole packs, not pack price alone. Confirm product compatibility and a workable laying pattern before treating the options as interchangeable.
Fixed comparison in metric units. Values are illustrative unless linked to a recorded project; changing the calculator above does not change this example.
Formula
Packs = net area × (1 + waste ÷ 100) ÷ installed coverage per pack, rounded up.
Worked examples in metric and imperial units
Illustrative values match Reset example and stay fixed when you edit the calculator. Both columns describe the same calculation; converted inputs are rounded.
Metric worked example
- Total surface area
- 24 m²
- Coverage per pack
- 2.2 m²
- Waste allowance
- 10 %
Flooring packs to buy: 12
Imperial worked example
- Total surface area
- 258.3339 ft²
- Coverage per pack
- 23.6806 ft²
- Waste allowance
- 10 %
Flooring packs to buy: 12
Follow the calculation
- Area including allowance = 24 × 1.1 = 26.4 m².
- Divide by 2.2 m² installed coverage per pack or roll, then round up to a whole purchase unit.
